Description

The The invention relates to a rotary piston engine according to the preamble of claim 1

State of the art

From the DE 4 26 366 A1 a rotary piston engine is known in which two units of the same type, which are suitable as a motor and compressor, are interconnected, with one, with the sequence of movement of a rotating crank loop, fitted in a rotating cylinder drum lock slide pushes the eccentrically mounted rotary piston via a rotary push joint.

The Sealing between the pressure differences is achieved by sealing strips, which are located in a fitted rotary piston reached. This simultaneously controls the change of charge during circulation Covered holes, located in the rotary piston and in the partition wall are located.

From the DE 42 29 999 C2 a rotary piston engine is known in which the seal on the abutment by a fixed sleeve, which is achieved by compression springs, which are located in the eccentric axis.

at The rotary piston engine according to the Wankel principle rotates an eccentric stored rotary piston in a fixed housing with Inner contours and produced with sealing elements that are in one Triangular flasks are located for the motor principle required working spaces.

Criticism of the state of the art

Of the Charge change caused by the bored holes, that are located between the engine and the compressor, be through the acting as a bypass fit gap of the rotary piston while the entire cycle shorted and therefore are considered a leak.

Of the Pressure on the abutment by spring pressure is in this arrangement because of the separating effect of the gas pressure broken.

The required for Wankel engine sealing elements are subject to high Speed of continuously changing tasks of migratory workspaces Gas pressure, heat and high mechanical stress.

task

It the task is to use the gas power in support of the To direct spring force so that in conjunction with an improved Kinematics an engine-capable Sealing can be done in training the workrooms and continue a driven by a crank disc control the gas exchange without Gap losses controls.

solution

The solution The object is in the preamble of the claim and in the Description described in detail with its design features.

1 shows the main view, wherein two units of the same type, as a compressor and engine own, with offset gate valve ( 5 ) on the partition ( 18 ) are screwed together to achieve a short charge path. The eccentric arrangement of the rotary piston to the cylinder drum is via the frame ( 10 ) and the rotatable eccentric sleeve ( 8th ) achieved in tandem arrangement. About the fixedly connected to the rotary piston outwardly guided axis of rotation, the gas through the inlet channel ( 13 ) in the working space ( 14 ) sucked by the compressor, then after compression via the control disk ( 15 ) at the right moment to get into the workspace of the engine, and then after closing the overflow channel ( 17 ) to ignite. On the description of cooling, lubrication, output and ignition was omitted because they are known and in DE 42 29 999 C2 are described.

2 shows the main picture as in 1 , wherein the eccentric arrangement is achieved by the rotary piston to the cylinder drum via a continuous space-fixed supported axis of rotation, and the automatic actuation of the eccentric sleeve, as in 8th shown, takes place as a connecting member between rotary piston on the abutment within the cylinder barrel. 4 shows the mechanics of the gas exchange control, where the control disc ( 15 ) axially by gas and spring pressure ( 24 ) frictionally with the partition ( 18 ) and as in 3 and in the kinematic scheme ( 11 ), which controls the gas exchange. 6 shows a further embodiment of the compression spring mechanism for the eccentric sleeve ( 8th ) with crank ( 22 ) and the basic adjustment ( 21 ), which is responsible for the pressure on the abutment, the holding seal following the rhythmic pressure buildup, as in 7 described, takes place.

7 shows a cross section of the compressor side 1 with enlarged zoom section ( 7a ) and in the kinematic scheme ( 13 ) illustrated effect of the rotatable eccentric sleeve at pressure, spring force and free-running, which affects the rotary piston on the abutment by applying or lifting.

8th . 9 and 10 are in the mode of action like 7 , but task-specific with other base points and eccentricities, and are shown in the attached enlarged figures and kinematic schemes.

10a shows the enlarged zoomed area 5 with split swivel joint ( 6 ), which is always positively connected with positive pressure or negative pressure with the contact surfaces of the locking slide and the cylindrical bore of the rotary piston.
